Claims. (Cl. 131-194) My invention relates broadly to the art of tobacco and more particularly to an appliance for pipes.

One of the objects of my invention is to provide an appliance for pipes for improving the smoking efiiciency and the convenience of use thereof by the attachment of a heat dissipating jacket around the stem and bowl of the pipe.

Another object of my invention is to provide a construction of flexible and resilient jacket for application to the stem and bowl of pipes for facilitating the conduction and radiation of heat for thus insuring the cooler operation of the pipe.

A further object of my invention is to provide a construction of cover of high porosity for snugly engaging the stem and bowl of a pipe for increasing the conduction and radiation surface about the pipe for therefore improving the operating efiiciency of the pipe.

Still .another object of my invention is to provide a construction of coarsely woven or knitted jacket for the stem and bowl of pipes which will sustain a pattern thereon for matching the pipe with the patterns in associated equipment or attire such as a tobacco pouch, necktie, belt, cap, Wristband, and other garment components.

Still other objects of my invention are to provide structural attachment means between opposite ends of a jacket for insertion over the exterior of a pipe bowl and stem and for maintenance of the jacket in position in engagement with the end of the bowl and with the junction of the pipe stem and the mouthpiece which connects with the stem.

Other and further objects of my invention reside in the structural arrangement and connection of parts of a jacket for a pipe bowl and stem which will insure the snug fitting of the jacket around the pipe bowl and stem as set forth more fully in the specification hereinafter following by reference to the acompanying drawings in which: Fig. 1 is a side elevational view of a pipe equipped with the attachment of my invention which in this embodiment is a jacket formed from a seamless knitted tubing;

Fig. 18 is a view of a further modified form of connecting means for the parts of the jacket using a lacing device for lacing the parts together in a manner conforming with the shape and contour of the stem and bowl of the pipe.

My invention is directed to an attachment for pipes in the form of a loosely knitted or woven or otherwise prepared jacket which fits around the pipe stem and bowl and provides means for conducting away and radiating the heat generated in the pipe during smoking and also to provide a finger protector for handling the pipe while hot and, in addition, providing a surface which may be ornamented in distinctive patterns to match associated wearing apparel or tobacco accessories. For example, the pattern presented by the attachment may match the pattern displayed in a tobacco pouch, or, the pattern may be the same as that in the user's necktie, belt, cap, wristband, socks, or other garment components. Such pattern lends itself particularly well as a display for collars and school insignia and colors. I employ various methods of attaching the device to the pipe as hereinafter explained in more detail.

Referring to the drawings in more detail, the smoking .pipe is illustrated as including the bowl 1 and the stem 2 having a screwthreaded recess 3 in the end thereof for receiving the coupling member 4 for connection of the stem 2 to the mouthpiece 5. The coupling member 4 is screwthreaded on each end thereof as represented at 6 and 7 where the screwthreaded extension 6 engages screwthreads in the recess 3 of the stem 2 and the screwthreads ed extension 7 engages screwthreads in the recess 8 of the mouthpiece 5. The coupling member 4 has a flange 9 thereon providing an abutment with the end of the stem 2 and a surface against which the flexible jacket of my invention may be clamped by the end surface 10 of the,

mouthpiece 5. The jacket of my invention is shown at 11 and may be a rubberized asbestos fabric which is stretchable and elastic or resilient and which is formed as a seamless tubular knitted product which is conformable to the shape and contour of the bowl 1 and stem 2 of the pipe. In Figs. 1-12 I have shown the jacket as a loosely knitted or woven seamless tubular product, but, as will be seen in Figs. 13-16, the jacket may be formed in two parts 12 and 14, shaped to correspond with the shape of the bowl and stem of a pipe. These two parts are externally stitched at 15 and 16 as shown more clearly in Fig. 14. These parts, 12 and 14, after being stitched, are reversed in position, as represented in Figs. 15 and 16, so that the seams are inside the jacket and thus improve the appearance of the device as a smooth exterior is presented to the viewer. Also the inturned flanges, stitched at 15 and 16, directly contact the exterior of the bowl 1 and stem 2 of the pipe, and facilitate conduction of heat out of the bowl 1 and stem 2 and into the jacket for radiation therefrom. Whether the jacket be formed as a seamless tube or a two-part casing, the material in both instances is stretchable and elastic or resilient. I may form the jacket from plastic threads. In order to render the jacket fire resistant the jacket may include a substantial amount of asbestos thread knitted or woven into the material. The fabric is thus substantially fire resistant, or has such a low rate of combustion as not to introduce any appreciable fire hazard with respect to the products of combustion in the pipe barrel.

The jacket 11 is secured in position on the pipe in a variety of ways. In Fig. 8 I have shown a grommet 17 clamped to the inturned end of the jacket 11 with an opening 18 extending through the grommet sufiicient for the passage of the externally threaded extension 7 of the coupling member 4. The end of the jacket 11 may thus be clamped between the end surface '10 of mouthpiece 5 and the flange 9 of the coupling member 4 for securing the end of jacket 11 with respect to the stem 2 of the pipe. The other end of the jacket 11 is clamped in an annular grommet 19. This grommet as shown in Figs. 1, 2, 3, 5, and 6, carries, on the external surface thereof, diametrically opposite radially extending pintles 20 and 21. In order to clamp the end of the jacket 11 with respect to the rim of the bowl 1, I provide an annular rim or ferrule 22 which fits over the rim of the bowl 1 and has a downwardly extending annular portion 23 which enters the mouth of the bowl and hugs the top of the interior wall thereof sufiiciently to provide an annular grip at the top of the pipe bowl. The rim 22 extends over the top of the rim of the bowl 1 and turns downwardly as represented at 24 and embraces the outside of the grommet 19. There are bayonet slots 25 and 26 provided in diametrically opposite positions in the downwardly turned portion or skirt of the rim 24 which are engageable with the pintles 20 and 21 on grommet '19 as represented, for example, in Figs. 1 and 2, thereby confining the grommet 19 and the jacket 11 connected thereto to the upper end of the bowl 1 of the pipe.

I may construct the attachment means in another way as illustrated in Fig. 7 where the grommeet 19' is not provided with pintles but, in lieu thereof, the exterior surface of grommet 19' is formed with screwthreads rep resented at 27. Under these conditions the rim device is not provided with bayonet slots, but is constructed as shown at 28 in Fig. 7, where the outside skirt 29, is provided with screwthreads 30 which engage the screwthreads 27 in the grommet 19 for fastening the jacket 11 at the top of the rim of the bowl 1. The rim 28 has an inwardly extending central portion 31 extending into the interior of the top of bowl 1 in a manner similar to the structure of the inwardly turned portion 23 of the form of my invention shown in Figs. 2, 5, and 6 for thus anchoring the top of the jacket 11 to the top of the bowl 1.

I have heretofore explained that various methods may be employed for securing the grommet 17 in position with respect to jacket 11. These same methods may be employed in securing grommet 19 in position, that is to say, the grommets may be pinched or clamped over the opposite ends of the jacket 11, as represented in Fig. 8; or the grommets such as 17 in Fig. 9, may be filled with adhesive, cement, or glue, indicated at 32 into which the end of the jacket 11 extends and is fixed in position; or the ends of the jacket 11 may be hemmed as represented in Fig. 10 by turning the end of the jacket 11 inwardly as represented at 33 and cross-stitching the hem as represented at 34. This reinforced hem may be stiffened for sustaining the jacket 11 at opposite ends thereof around the barrel or stem of the pipe.

The jacket 11 is readily interchangeable to match various patterns or colors such as fraternity insignia, etc. In the case of the seamless, tubular construction illus trated in Figs. 1-12, the mouthpiece 5 is removed and then the seamless, tubular jacket drawn over the stem 2 and the enlarged end of the jacket snugly fitted around the bowl 1 and the end of the jacket embraced by grommet 17 clamped in position by attaching the mouthpiece 5 as heretofore explained. The barrel end of the jacket is then secured in position by the rim connecting means such as that shown in Figs. 1, 2, 5, and 6, or the means shown in Fig. 7. However, where the jacket is formed in two parts, as explained in connection with the construction shown in Figs. 13-16, the two parts 12 and 14 may be connected together as represented in Fig. 17 by means of a zipper 35, or the two parts 12 and 14 may be interconnected by a lacing cord 36 shown in Fig. 18, which adds ornamentation to the jacket where the cord passes through small eyelets or slits provided in the parts 12 and 14.

Figs. 11 and 12 represent more clearly the performance of a pipe equipped with the jacket of my invention where the arrows 37 indicate the direction of heat radiation from the exterior of the barrel 1 and stem 2, where the heat is conducted through the fabric 1 and then radiated from the surface thereof for maintaining the operation of the pipe at a relatively uniform stabilized temperature.

While I have described my invention in certain of its preferred embodiments, I realize that modifications may be made and I desire that it be understood that no limitations upon my invention are intended other than may be imposed by the scope of the appended claims.
